Illuminated Waterproof Button Front Cover for ESP32 4-Channel Relay Module Enclosure

This remix replaces the original front panel and custom LED PCB with four standard 12 mm illuminated waterproof push buttons. The buttons connect directly to the ESP32 GPIOs, while the LED rings use the relay GPIOs to indicate the relay status.

It's a simpler build that requires no custom LED PCB and is ideal if you prefer using readily available off-the-shelf components.

Features

• No custom LED PCB required
• Uses standard 12 mm illuminated waterproof push buttons
• Built-in LED ring indicates relay status
• Same enclosure and ESPHome configuration as the original design
• Great for workshop, garage, or outdoor installations

Note: This remix only includes the alternative front cover. All other enclosure parts are the same as the original project.

Required Hardware

• 4 × 12 mm illuminated waterproof push buttons (3V–6V LED version)

Important: Do not use the 12V LED version, as the LED rings are driven directly from the ESP32 GPIO pins.
